Answer:
Step-by-step explanation:
B. :) 6(a) -6(3) is the same as 6 (a - 3) which simplifies to 6a-18. If I helped, please mark as brainliest! <3
The answer would be 28x+30.
You can do this by doing long division.
<u>Refer to the attachment please.</u>
The final quotient will then be 3x - 11 remainder 28x + 30
Answer:
a) 5000 m²
b) A(x) = x(200 -2x)
c) 0 < x < 100
Step-by-step explanation:
b) The remaining fence, after the two sides of length x are fenced, is 200-2x. That is the length of the side parallel to the building. The product of the lengths parallel and perpendicular to the building is the area of the playground:
A(x) = x(200 -2x)
__
a) A(50) = 50(200 -2·50) = 50·100 = 5000 . . . . m²
__
c) The equation makes no sense if either length (x or 200-2x) is negative, so a reasonable domain is (0, 100). For x=0 or x=100, the playground area is zero, so we're not concerned with those cases, either. Those endpoints could be included in the domain if you like.
Answer:
4%
Step-by-step explanation:
R=INTEREST X 100% / TIME X PRINCIPAL
r=40 x 100=4000
4000/500 x 2=1000
4000/1000=4%
Hey there!
I'll assume we're using the slope-intercept form equation:
y = mx + b
m = slope
b = y-intercept
First, we keep the y, because it's value depends on the x value given.
Next, we find the slope. Slope is defined as rise/run, so we take two points on the graph, find how much taller one is from another, and how far right/left they are, put those values over each other, and we have out slope (m).
Finally, we need to determine the y-intercept, and that's as simple as seeing where the line crosses the y axis and writing down that value.
Hope this helps!
